What this chart really says is that those who hold BitUSD really like
interest and are comfortable letting their BitUSD ride.
CCEDK has a sold buy wall for BitUSD / USD and no one selling for real USD. This means that BitUSD holders are happy to hold.
The only incentive we have to get BitUSD holders to sell is to give them more than $1.00.
Remove the interest and there will be less incentive to hold BitUSD which will help the shorts out some.
